What should I do if there is a blurred screen?

Method:

1. The horizontal or vertical bar is displayed, which is generally the LCD cable (note that it is the LCD line, there is only one layer, directly connected to the LCD (display screen) under the glass mirror) is broken, and it is difficult to repair, unless it is a technician who produces LCD screens.

2. The cloud-like spotted screen is definitely the LCD is broken, and it has not been repaired, so it will be scrapped and replaced.

3. Occasional garbled characters during startup or use.

Images or text are out of order), there may be a variety of reasons, the software is most likely to be broken, and it is generally better to flash it. In addition, it is possible that the CPU is bad, and the font IC flash is also bad, and this fault can generally be repaired.

The mobile phone screen, also known as the display screen, is used to display images and colors. The size of the screen depends on the screenDiagonalCalculations, usually measured in inches, refer to the diagonal length of the screen. With the gradual popularization of mobile phone color screens, the material of mobile phone screens is becoming more and more important.

The color screen of mobile phones varies due to different LCD quality and R&D technology, and its types are roughly TFT, TFD, UFB, STN and OLED. Generally speaking, the more colors that can be displayed, the more complex images can be displayed, and the more layers of the picture will be.

Most of the screen is biased towards driver problems, but it also excludes the problem of screen lines contacting the motherboard. We recommend that you perform the following troubleshooting:

1. System setting problem, it is recommended to restore the default factory settings.

2. If the screen is still blurred, it is recommended to re-flash the machine.

3. If it is still a blurry screen, the screen module is reassembled, if it is still a blurry screen, most of it is a motherboard problem, and it can be returned to the factory for repair.

Look at whether it is the outer screen or the inner screen, the bad inner screen needs to be replaced, but the bad outer screen only needs to be replaced with the outer screen.

It should be that the inner screen is broken, and it is recommended to replace the inner screen.

The display is broken, it is recommended to replace it with a new one.

If the screen is blurred, it is usually the LCD screen that is broken, and the screen can only be replaced.

1. The mobile phone has been dropped, bumped, or used for many years. may cause damage to the phone cable. It is recommended to send it to a mobile phone store or after-sales maintenance to replace it with a new mobile phone cable.

2. It may be due to water or bumps that cause the screen in the mobile phone to be broken. It is recommended to send it to a mobile phone store or after-sales repair to replace it with a new screen in the phone.

3. There may be a problem with the current system firmware of the Apple phone. It is recommended to redo the system firmware of the mobile phone, or update and upgrade the new version of the system.

4. It is recommended to bring the equipment to the after-sales center (020-83621957) for maintenance and processing, and make an online appointment to waive the service fee.

If you are using a Huawei smartphone and you find that the screen suddenly appears on your phone, such as a splashed screen or a splashing screen, you can troubleshoot the following items:

If your phone's screen display suddenly appears blurred or flickering.

It may be due to the interference of human static electricity on the display signal when the environment is dry, the mobile phone system has an automatic error correction function, and the display will return to normal within a few seconds, if it does not return to normal, please try to restart the mobile phone and recover.

If your phone only appears when you use an app, the screen will appear splashed or splashed.

This may be an application compatibility issue (for example, if some software is not compatible with the format, the screen will be blurred due to decoding errors), so we recommend that you uninstall the app and use it in the relevant app in AppGallery or other apps of the same type.

The above methods still can't solve the problem.

If the above methods do not solve your problem, we recommend that you back up your data in advance (third-party apps such as QQ and WeChat must be backed up separately) and bring the relevant purchase voucher to a nearby Huawei Customer Service Center for maintenance.

1.Streaks on the computer screen: There are two main reasons for this:

1) External interference, such as electric sparks or high-frequency electromagnetic interference near the use site of the display, this interference will cause the display screen of the display to produce white horizontal stripes. Solution: Avoid using the monitor in this situation;

2) Internal interference, this interference will make the display screen of the display appear black horizontal stripes, in this case, you can open the case to check whether there is a bad contact inside the display, whether there is a problem with the output end of the power supply or the output transformer, etc., because the reasons for this situation involve more professional technology, so it is best to ask a professional to repair it.

2.Improper display resolution setting causes streaks on the computer screen: When the display is not set correctly in the resolution of win95, there may be a computer screen flower screen failure when starting Windows, that is, the picture is layered, shaking, serious and even black screen of death.

Solution: Enter the setup or enter the security mode of win95, and reset the display mode of the display.

3.Conflict between the graphics card and the Chinese system: In this case, when exiting the Chinese system, the computer screen will appear, and there is no response to random keystrokes, similar to a crash, processing method: enter modec080 at this time to be solved.

4.Poor heat dissipation effect of the main control chip of the graphics card: This will also cause streaks on the computer screen, and the treatment method is to improve the heat dissipation performance of the graphics card.

5.The video memory speed is too low: When the video memory speed is too low to match the speed of the host, the computer screen will also be blurred.

6.Video memory corruption: When the video memory is damaged, there will be a blurred screen when the system boots up.

7.Virus cause: Some viruses will also appear when the screen appears, and the solution: use antivirus software to eliminate it.

Summary. Hello dear,The reason is the stripe or patterned screen phenomenon,Open the chassis after shutting down,Take out the memory module,Wipe the gold finger of the memory module with a rough eraser,Then reinsert it,Then turn it on and try again,The phenomenon of the screen may be eliminated immediately。 This situation is caused by the fact that the gold finger of the memory module has not been wiped for a long time, resulting in the growth of patina on the gold finger of the memory module and the poor contact with the motherboard card slot.

The phenomenon of stripe-shaped, textured, and square-shaped screen may also be the problem of graphics card failure and gold finger contact of the graphics card.

I'm a laptop.

If there is such a situation, you should turn off the computer in time to let the computer rest for a while, so that the graphics card of your laptop will be buffered slowly, otherwise the graphics card will be damaged after long-term use. In addition, the screen of the notebook computer should be wiped frequently, so as to ensure the cleanliness of the laptop screen, because once the screen enters the dust, the chip of the laptop screen will be damaged, and this kind of chip is relatively fragile, and once damaged, it cannot be restored, so it is very important to keep the laptop screen clean.

I think it's a wiring problem.,Just turn it on and move the screen a little.。

But I'm not sure.

You try to turn off the computer and let the computer rest for two hours, and if there is still this problem, consider the cable failure.

Summary. The screen is blurred one by one, which may be caused by poor screen connection, loose data cable, etc. If you encounter this situation, you can first check whether the data cable is loose and whether it is connected normally.

If there is no problem with the data cable, you can try to power off and restart the computer or change to a clean data cable to try again. If it still doesn't work, it may be caused by hardware problems such as the graphics card, and you need to find a professional to repair it. At the same time, we should also pay attention to maintaining good usage habits, avoid playing games or using the computer for a long time, and reasonably adjust the screen brightness, color temperature and other parameters, which can effectively reduce the possibility of screen problems.

The screen is blurred one by one, which may be caused by poor screen connection, messy and loose data cables, etc. If you encounter this situation, you can first check whether the data cable is loose and whether it is connected normally.

Streaks on the computer screen: There are two main reasons for this:

1. External interference, such as electric sparks or high-frequency electromagnetic interference near the use site of the display.

This interference can cause the display of the monitor to produce white horizontal streaks, so avoid using the monitor in this case.

2. Internal interference, this interference will make the display screen of the display appear black horizontal stripes, in this case, you can open the case to check whether there is a poor contact inside the display, whether there is a problem with the output end of the power supply or the output transformer, etc., because the reason for the macro branch production in this situation involves more professional technology, so it is best to ask a professional to repair it.

Introduction: To maintain a computer monitor, you need to pay attention to avoiding dust and removing dust regularly. Dust is highly attractive to dust particles in the air, and its deposition can affect electronic components.

heat dissipation, corrosion of electronic circuits, etc. When you turn off the power to remove dust from the monitor screen, remember to turn off the power to the monitor and unplug the display power cord and signal cable.

Clean the slag-sensitive mirror surface with a special mirror wipe paper for beam molds, dry face paper, dry flannel cloth or a wet flannel cloth dipped in a small amount of water, and carefully wipe it from the center of the screen outward.
